Park Passive

Park Passive

Park Passive is Cascade Built’s most energy efficient project to date. Designed by Nicholson Kovalchick Architects, the 2,710 square foot single family home located in Seattle’s Madison Park neighborhood is Seattle’s 1st certified Passive House, meeting the rigorous standards of the PassivHaus Institut by reducing heating energy consumption by nearly 90%.

Jokingly, we tell people we plan to heat the house with a hairdryer, though that does represent the approximate level of heat needed, as a result of extreme attention to detail in air sealing, high levels of insulation, and high-performance windows. The 4bd/3ba home also features salvaged Ash woodwork from a site harvested tree, zero VOC finishes, a heat recovery ventilator and more. True to our style, this beautiful home is built on an in-fill city lot that measures just about 2,000 SF. The Passive House consultant is Rob Harrison of Harrison Architects.
